HAND FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 320,425, dated June 16, 1885.

Application filed January 2S, 1885.

To all whom it 'may concern` A Be it known that I, JAMES S. ZERBE, of' Hartwelhin thecouutyot' Hamilton and State of Ohio, have invented a new and useful Improvement in Hand Fire-Extinguishers, which improvement is fully set forth in the following specification and accompanyingdrawings, iu which- Figure 1 is a perspective view ofa complete hand fire-extinguisher. Fig. 2 is a sectional view ofthe same enlarged; and Fig. 3 is a view ofthe ejecting end,showin g the plunger withdrawn from the head.

The object of my invention is to construct a hand fire-extinguisher, by means of which the liquid within the tube can be readily ejected when desired, in case ofiire.

lThe particular feature ofthis invention consists in employing a tube or cylinder having a plunger or piston-rod bearing a piston and a loose disk, which rod passes entirely through both heads of the tube or cylinder, said rod or handle being soldered to the heads, so as to hermetically seal the tubeA to prevent leakage, whereby when the rod is turned or Wrenched the soldered parts willgive way, producing an opening at one end for the ejection ofthe fluid, and at the same time permitting the plunger to be reciprocated, all ot' which will now be fully set forth in detail.

In the accompanying drawings, A represen ts a tube or cylinder of any suitable size having at the ends the plain heads B C. .The head I3, which is at the forward end of the tube, has centrally a perforation, D, adapted to receive tightly the forward end ofthe plunger or piston rod E, as shown in Figs. 1and2. The head C at the rear end of the tube has also centrally an opening, so as to readily admit the rod F. The piston-rod E has a disk or piston, F, secured to it near its forward end, having perfo-rations or openings through it, and this disk is soldered or attached firmly to the rod. Sliding on the rod on the forward side of this disk is a smaller disk, G, which acts as a valve when the rod is moved backward or forward. The aperture D, through the forward end of the tube A, is closed by the forward end of the rod E and hermetically sealed by solder.

In operation the rod or plunger E is inserted with its disk F in the cylinder of tube A, so

(No model.)

that the forward end of the rod projects through the head B in the aperture D, and the forward end of the rod E is soldered to the head B, as shown in Fig. 2, while the rod at the rear end is soldered to the head C, as shown at LI. Either one or both ot' these ends may be soldered before the liquid is placed inthe tube; but in any event after sealing the ends to the rod or plunger, the liquid is to be placed into the tubes by means ot' an independent aperture, or through one ot' the heads, if desired, and afterward hermeticall y sealed. ln this condition the device is ready for transportation and for use when desired.

The instrument is used. by turning the rod E and loosening the solder at the end of the tube A. This releases the said rod and allows it to be reciprocated in the tube for the purpose of injecting the lire extinguishing tluid. By this movement also it will be observed that the opening Dis uusealed, and as the plunger is moved forward the liquid is forcibly expelled through the opening thus made. As it is frequentiy'the case that the device will be placed or Illing up in a room where lires are likely to occur, andas it is of the utmost importance that the liquid within should be freed, itis designed to hang the device upon a nail by means of loop or handle I.

If thedtvice is to be suspended by the han die I, so that it will operate automatically by heat, the rod E should be soldered at the apertures through the ends of the tube A by a metal or compound which is fusible at a low temperature. Thus, when said solder melts, the tube A will descend andV permit the liquid to iiow from the aperture D.

Having described my invention, what I claim as new isl. A portable lire-extinguisher consisting of a tube, A, a piston-rod provided with a perforated piston and a loose disk or valve, a perforated head, B, adapted to receive the end of the pistonrod, and the latter held by means of solder applied substantially as described.

2. In a hand lire-extinguisher, the tube having at each end a plain head centrally perforated, provided with a plunge-r or piston rod within having at its outer end the handle I and on its inner end the head F and valve G, said rod resting in the apertures or open ings of the heads, so that when said plunger IOO or rod is soldered to the said heads the tube will be hermetieally sealed, substantially as herein set forth.

4. In a hand tire-extinguisher, the tube A, having` the plain heads B C centrally perforated, in combination with the plunger or piszo 3. In a hand lire-extinguisher, the piston l ton rod E within said tube and Secured inthe 5 rod or plunger within the tube having` asuit central orifices of said heads or ends bylneans f able head and valve within, with the opposite i ot' fusible solder or otherwise,said rod having ends ot' said rod resting and closing` up the a perforated head and valve, and on its outer central orifice of the headsand soldered t0 end the handle. the Whole arranged as and for z5 said heads by fusible solder, so that by a tori the purpose substantially as herein set forth.
